Longitudinal rugae on cephalic dorsum prominent, weakly wavy; in full-face view, medial rugae diverging weakly toward posterior corners of head. In profile, cephalic rugae converging approximately midway between posterior margin of eye and vertex. Cephalic interrugae moderately granulate, weakly shining; vertex weakly to moderately rugose, interrugae smooth, strongly shining. Anterior margin of clypeus concave; dorsal surface with numerous subparallel, longitudinal rugae. Mandibles with six teeth; mandibular dorsum coarsely rugose. Numerous moderately long, curved, bristle-like, cream to light yellowish hairs project from basolateral margin of mandibles. MOD = 0.21x HL. In profile, eyes situated near middle of head, OMD = 1.30x MOD. Scapes missing; scapes not reaching vertex as per Forel (1899c). Psammophore well-developed.
